Glean

Enterprise search and AI assistant built on a company's own documents and systems

Overview

Glean indexes a company’s documents, tickets, messages and applications and lets employees query them through search, an assistant and agents, with access controls carried over from source systems. The company announced on 28 May 2026 that it had surpassed US$300 million in ARR[21]. Its most recent priced round on its own site is a US$150 million Series F at a US$7.2 billion valuation, led by Wellington Management and announced on 10 June 2025, when ARR had passed US$100 million[22]. Glean belongs to a group of application companies that rely on third-party models and differentiate on data connectors and permissions. Its limitation is that cloud-suite vendors bundle comparable assistants into existing licences.
